I would suggest you try it (paper trade it, not real money) and you may learn something useful.

It seems to me that with any strategy there is an element of randomness, so the articles seem to be comparing strategies with different degrees of randomness. How random is the strategy that is examined in the articles? Is it that the system goes long on a randomly selected stock...or that it randomly selects a stock and then randomly chooses long or short at a random time?
